Pulse encoder receiver
Two different incremental encoder connections are available.
-differential connection; pulse encoders generating either voltage or current signals
can be used
-single-ended (push pull) connection; voltage signals
Restrictions using jumper S4 (CON-4): or S10 (IOB-3): depending on the board
Line termination via S4/S10 should not be used at 12 V or 24 V encoders, because
of the power consumption taken from the encoder. If a pulse encoder with a build in
current source is used a burden resistor of 120 Ω is activated via jumper S10: 1-2 on
SDCS-IOB-3 a.s.o.
Pulse encoder connection principles
In case of a single ended 5 V encoder the jumpers S4 / S10 will be set to a neutral position. To get a threshold lower than 5 V each
terminal X5:2 / X5:4 / X5:6 must be connected via a resistor R to GND.
In any case, if SDCS-IOB-3 is used, see required settings of SDCS-CON-4
